Deformity correction and fracture treatment using the software-based Ortho-SUV frame

In the correction of complex multi-component and multi-planar deformities (Tables 16.1 and 16.3) using the Ilizarov frame, unified reduction nodes have to be replaced three to five times (Fig. 17.1) [368]. Every frame re-assembly involves a change in the reductional units and is a highly laborious process in which there is additional patient exposure to radiation. Sometimes, due to the peculiarities of frame assembly (external supports are not oriented at a right angle to the axes of the bone fragments, a bone is not at the center of a support, the support for some reason is not closed, etc.), correction of one component can lead to the secondary translation of other(s). These secondary translations will, in turn, require correction and therefore additional frame re-assembly.
